DEEP TECH, TECHNOLOGY IBM’s 7 Angstrom Chips Boost Efficiency by 70% Over 2nm June 26, 2026 BY IVY DELANEY IBM has unveiled a computer chip built with transistor nodes measuring 0.7 nanometers, or 7 angstroms wide. This achievement marks the first time transistors at this scale have been realized, surpassing the current industry standard of 2 nanometer chips. In a chip the size of a fingernail, t

On June 25, IBM unveiled what it calls the world's first sub-1nm chip technology: a 0.7nm — or 7 angstrom — transistor architecture built on an entirely new 3D platform called Nanostack. The announcement, timed to the VLSI 2026 symposium, marks the first time logic technology has extended below the 1nm node and, IBM says, opens a roadmap of at least a decade of further semiconductor scaling.
